COLLAR-BUTTON.

BPECIFICATION forming part of Letters Patent No. 311,107, Med January20, 1885.

Application filed November 522, 1884. (No model.)

To all whom it may concern:

My present invention is an improvement thereon; and it consists inconstructing the back double, as hereinafter described.

I propose constructing the said back either with or without a smallcentral aperture C0111- municating with the post, and in accompanyingdrawings both modes of construction are represented, Figures 1 to 4,inclusive, exhibiting one mode, and Figs. 5 to 8, inclusive, the other.

I will preface further description of these modes of manufacture bystating that, inasmuch as they involve per so nothing essen-' tiallynovel, save in respect to the result or article produced, I omitdetailed description of the special successive manipulations required todraw or swage the blank into the ultimate forms desired, since they (themanipulations) are well known, as will be readily understood or devisedby those skilled in the art.

Referring, then, in the first instance, to Figs. 1 to 4, inclusive, Iwill state that the first step in the process of manufacture of a buttonhaving a double back with a central aperture therein consists in drawingor swaging a blankto wit, a thin metal disk-into the form represented byFig. 1,wherein the hollow post a is shown projecting from the flat upper(or inner) portion of the back b,whose. outer (lower) portion yetremains to be formed from the pendent circular flange c. In the nextswaging operation this right-angular flange c is upset and deflectedinward at an acute angle, as shown in Fig. 2, and by the next twooperations it is reduced to parallelism with the inner (upper) portion,as illustrated. in Figs.

3 and 4. Thus a collar-button is produced (see-Figs. 6, 7) until theform shown in Fig.

8 is attained that is to say, a double back, 1), whose face or outer(lower) portion is entire or without an opening. Thus, by either mode ofmanufacture above described I produce a collar-button whose back isdouble and yet solid, or in one piece with the hollow post, and whichis, therefore, superior in the important qualities of solidity,strength, du-

rability, and ornamental finish or effect.

It is obvious that sleeve-buttons of a certain class may be manufacturedin the same manner and form as collar-buttons.

What I claim is 1. The improved collar-button, substan' tially asdescribed, the same consisting of the double back and hollow post formedin one piece, and said post being provided with a suitable head.

2. The collar -button having a double or hollow back, 1;, which isformed entire or without an opening therein, and in one piece with thehollow post, a, which is provided with a suitable head, substantially asshown and described.
